Method and Device for Filtering Network Traffic

摘要

The invention relates to a method for filtering network data in a network node, comprising the steps of producing filter markings in a grammatical structure of network data encoded by means of an encoding scheme on the basis of adjustable filter inquiries of at least one further network node, producing a filter mask on the basis of the filter markings, receiving a data flow encoded by means of the encoding scheme in the network node, filtering the data flow by means of the filter mask, and forwarding the filtered encoded data flow to the at least one further network node.

主权项

1. A method for filtering network data in a network node, the method comprising:
producing filter markings in a grammatical structure of network data coded using a coding scheme based on adjustable filter queries from at least one further network node; producing a filter mask based on the filter markings; receiving a data stream coded using the coding scheme in the network node; filtering the data stream with the aid of the filter mask; and forwarding the filtered coded data stream to the at least one further network node.
